COST INDICATING, REGlS-TRlNG, AND WEIGHT-TOTALING APPARATUS FOR WElGHlNG-IVIACHINAS.

SPECIFICATION forming part of Letters Patent No. 646,578, dated April 3, 1900.

Applicaticn filed December 23,1898. Serial No. 700,156. rtllo modeld 'b all whom t may concern.:

Be it known that we, WILLIAM HICKLEY GUNDRY and WILLIAM LEONARD DEIGIITON GUNDRY, subjects of the Queen of Great Britain, residing at 183 Hereford street, Christchurch, in the provincial district of Canterbury, New Zealand, have invented Improved Cost Indicating, Registering, and Vtfeight- Totaling Apparatus for Employment upon Veighing-Machines, ot which the following is a specification.

This invention provides apparatus for employment upon or in connection with leverplatform weighing-machines to indicate the cost of an article weighed upon the scale at any one ot a number of predetermined prices per unit of weight. The cost of every article weighed is also recorded upon a traveling band of paper and totaling mechanism is actuated which indicates the total weight of articles weighed upon the machine at one or a plurality of weighings. The cost-indicating apparatus consists of a disk dial revoluble behind a fixed screen and bearing upon its face a number of radialcolumns of figures, the figures in each column representing the cost of' articles of one weight at different prices. The dial is revolved by mechanism from the weighing bob upon the lever arm of the weighingmachine, and when an article is weighed the'radial columnvof cost-markings representing the cost of articles of that weight at different prices per unit is brought into a vertical position above the axis of the dial and in line with a slot cut in the screen referred to. A cover-plate caused to slide over the vertical column of figures has an aperture through which only one cost-marking is visi-l ble at a time, and the cover-plate is held, when this aperture is in correct position, by one of a number of horizontal bolts placed one above the other, and either of which may be operated to engage a projection upon the coverplate. In the recording mechanism the back of the dial has figure-markings in bas-relief corresponding exactly with the `figures upon its face, this result being preferably obtained by stamping the figures so that they appear in recess upon the face and in relief upon the back. A traveling band oi paper is pressed by a roller against the figures at the back of the dial corresponding with those seen through the aperture in the cover-plate upon its face, the paper being marked by a carbon or ink ribbon interposed between it and the figures.

The weight-totaling mechanism consists of an ordinary counter which is driven by a spurwheel upon the dial-axle, a toothed pinionwheel of the counter being brought into gear with the spur-wheel after each weighing operation, as herein described.

lVe will more particularly describe our invention and the operation thereof by the aid of the accompanying drawings, wherein- Figure lis a front elevation; Fig. 2, asimilar view with part ot' the casing removed; Fig. 3, a rear elevation; Fig. 4, a plan; Fig. 5, a diagrammatic view ot' an arrangement for returning the dial to its normal position after a weighing operation.

'We will first describe the cost-indicating mechanism, with reference more particularly to Figs. l to 4, 12, 13, 18, and 19 of the drawings.

The weighing-machine weighing-bob l upon the lever-arm (both shown in dotted lines in Fig. l) has a recess r, which is almost straight, which receives a pin 2, projecting from a slideblock 3, said slide-block being movable hori- IOO zontally in guides 4 and the recess in the balance-bob shaped to allow the lever of the weighing-machine to vibrate during a weighing operation, while horizontal movement of the weighing-bob is communicated to the slide-block. A driving-band 5, formed of ribbon-steel,is connected at each end to opposite ends of the slide-block and after passing over guide-pulleys 6 is led over a sprocket-wheel 7, which has sprockets upon its periphery taking into corresl'ionding perforations in the driving-band. Sprocket-wheel 7is iixed upon a spindle 8, journaled in bracket 9, and said spindle has also a sprocket-wheel 10 fixed upon it, connected byadriving-band 11, similar to that described,with a sprocket-wheel12, fixed upon an axle 13, which carries the disk dial 14. The dial is provided upon its face and back with the same numberof radial columns of figures as the number of diterent weights the machine is calculated to deal with. The figures upon the face of the dial are to give visual indication only and may be produced by printing or analogous means; but the iigures upon the back of the dial are to be used as printing-type and are castin stereo-metal or india-rubber or by stamping the dial as described in the preamble hereto, so as to be in relief, and are arranged to read backward in the manner of printing-type. There are as many cost-markings in each radial column as there are different prices per unit of weight at which articles are sold, and the figures are arranged in regular order with the cost of au article of the lowest price nearest to the eenter of the dial, the next higher price immediately beyond it, and so ou.

In a Weighing operation when the Weighingbob 1 has been adjusted upon the weighingmaehine lever to the weight upon the scale then the dial has been revolved by the sprocket-wheels and driving-bands described until the radial column oi. .figures giving the cost of articles of that weight at different prices is in a vertical position above the center of the dial. The dial revolves behind a fixed screen-plate 15, the upper portion of which has a vertical slot 1G, over which slides a coverplate 17, having an aperturel 1S, through which onlyone of the cost-markings upon the dial is seen at a time. The aperture 18 is brought into correct position to expose the marking giving the cost of an article being weighed at a particular price in the following manner: The cover-plate 17 is connected by a bridge-piece 19 with a plate 20, which extends down the back ol the dialand is bifurcated to clear the dial-axle 13 and has brackets 21 xed upon either side, through which pass vertical guide-rods 22. The coverplate tends to slide vertically by reason of a weighted plunger 23, working in a cylinder 24 and provided with a cord 25, passing over a guide-pulley 26 and connected to a bracket 27 at the bottom of the plate 20. The coverplate 17 is retained in its normal position by a hook 28, which engages with a bracket 2f),

lixed at the bottom ot the cover-plate, said hook being carried byahorizou tal sliding bar 30, which has a number of cam-faces 3 Sliding bolts 32, equal in number to the dit ferent prices used, are arranged upon the screen-plate 15, the one above the other and upon each side at right angles to the coverplate 17, each being provided with a returning-spring Levers 34, one for each bolt, fulcrumed at 35 and engaging with a pin 3G upon the-bolt at one end and having a bevel `cam-face 37 at the other, are employed to operate one or other of the bolts and cause it to projectinto the path ot' the bracket 20, and thereby to stop the cover-plate in its vertical. travel when the aperture 1S is in correct position to disclose the cost of an article then upon the scale at a certain price. Push-buttons 3S, one for each lever, are each fixed upon a spindle 239, which. passes through the front ot' the casing 40, and a disk-cam 41 at the end of each spindle is arranged,wl1en the button is pushed inwardly, to contact with one of the cam-faces 31 and to slide the bar 30 longitudinally against the pressure of a returning-spring 42 and to thereby withdraw the hook 28 from engagement with bracket 2) and allow cover-plate 17 to rise under influence of the weighted plunger The cam 41 also at the same time contacts with one ol:` the bevel cam-'faces 37 and operates the lever to which it is attached to cause one of the bolts 32 to project into the path of the bracket 29. The push-buttons are cach marked with the particular price per unit oi' weight to correspond with the cost-marking exposed when it is operated. A spring 43, coiled around each of the spindles 30, between the casing of the apparatusand the push-button, insures their return at'ter an operation. The end oi each bolt is provided with a notch 44, into which a projection upon bracket 29 passes and prevents the bolt from passing back until the cover-plate 17 has been brought down in a manner to be described.

To prevent the possibility of apush-button being operated so quickly that its bolt returns from the path of the bracket 2f) before said bracket engages with it, locking-plates 45 (shown clearly in Figs. 12 and 125) are cmployed, which have holes corresponding with the number and diameter of the bolts and at the same distance apart. The locking-plates are connected together at their lower ends by a bracket 4G and tend to slide each over the face of the metal bars -1-7, through which the bolts operate, a spring 4S pressing upwardly upon bracket 4G. Normally the locking-plates are held down, so that the holes are opposite to the bolt-holes, by the bottom of the coverplate 17; but when a push-button is operated the rise of the cover-plate permits the plates 45 to slide upwardly a short distance and the locking-plate upon the lower side of the hole through which an operated bolt has passed engages in a notch 49, with which each oi' the bolts is provided, and prevents its return until IOO ' jecting from the lever-arm 63.

the locking-plates are depressed by the return of the cover-plate 17 to its normal position.

We will now describe the arrangement for returning the dial-disk and the cover-plate 17 to their Zero positions after the apparatus has been operated, referring more particularly to Figs. 5 and 20. Upon the dial-axle 13 is a drum 50, upon which a cord 51 is Wound by the forward revolution of the dial under a Weighing operation. The oord is carried around the tension-pulley 52, which has a weight 58 attached to it, and is then led over the guide pulley 5A and connected to a weighted plunger 55, Working in the cylinder 56. The plunger has a piston-leather 57 at its lower end, and a tap 58 near the bottom cf the cylinder permits air to be compressed beneath the piston-leather-and the rate of descent of the plunger to be thereby regulated. An air-admission valve 59 at the base of the cylinder allows air to pass in when the plunger is lifted. A spring-catch 60 upon the top of the cylinder engages in a notch 61 in the plunger when it is at the top of its stroke. A hand-lever 62, pivoted on a bracket 62a upon the casing of the apparatus, extends across the face of the dial and has a short projecting arm 63, which passes aroundand extends along the back of the dial parallel with said lever. A weight 641-, attached to a cord 65a, passing over the pulley 66 and connected to the lever 62, acts as a counterbalance for said lever. The plunger 55 has a pivoted upwardlyextending lifting-rod 68, passing through a bracket 63a upon the arm 64, referred to, and terminating with a nut 69. The plunger is prevented from turningin the cylinder by a rod 70, working through a iixed guide 71. The spring-catch 60 has a tailpiece 72, arranged to be engaged by a pin 73, pro- Before the commencement of a weighing operation the lever 62 is raised by a handle 74, th'erebylifting the plunger 55 by means of the liftingrod 68, until the catch 60 passes into the notch 6l, the slack cord between the drum 50 and the plunger 55 being taken up by the tensionpulley 52. When the dial is revolved by the adjustment of the weighing-bob upon the weighing-machine lever, the cord is Wound upon the drum 50, the shortening of the cord raising the Weight attached to the tension-pulley 52. lVhen the article has been correctly balanced upon the scale, the lever 62 is pulled down by the salesman, when the pin 73 upon arm 63 contacts with thegtailpiece 72 of the spring-catch 60 and the plunger 55 is released. The weight upon the tension-pulley is raised unt-il a stop 75 upon the cord 65 is retained by a catch 76, and the cord is unwound from the drum 50 as the dial revolves back to Zero.

YIt is required that until an article has been correctly balanced upon the scale the dial shall be revoluble in either direction and the weighing-bob 1, and consequently the slideblock 8 working with it, shall be capable of movement backward and forward; but directly the article has been weighed and the price push-button operated then the operator shall not be able to move the weighing-bob 1 backwardly until the lever 62 has been brought down to its full extent. This result is secured by the following arrangement illustrated in Fig. 11: The dial has notches 77 around its periphery, one opposite to each column of cost-markings, and one or other of them is always engaged by a spring-catch 78 unless said catch is pressed down by the bottom of the plate 20 referred to at the back of the dial. Consequently when the cover-plate is caused to rise in the manner before described the dial cannot be revolved until the cover-plate is returned.

Referring now particularly to Figs. 16 and 17, the sprocket-wheel 7 in front of the dial has ratchet-teeth 79 upon its inner face engaged bya pawl 8O upon a pivoted arm 81 and kept in engagement with the ratchet-teeth by a spring 82 around a spindle 83, projecting rearwardly from the arm 81, and provided with a pin 84, engaged by one end of a lever 85, pivoted at 86 upon the casing of the apparatus and having its other end projecting into the path of the lever-arm 63, by which it is operated to disengage the pawl from the ratchet-teeth When the lever is pulled down. A push-button 87, projecting in front of the pawl-arm 81, enables the pawl to be pushed out of engagement with the ratchetteeth when it is desired to move the weighing-bobv back upon the lever of the weighing-machine; but, as before described, when one of the price push-buttons has been operated then the dial is locked by one of the notches 77 and springcatch 78, so that if the pawl push-button 87 be operated the dial cannot be revolved back until the lever 62 has been pulled down.

To return the cover-plate 17 to its zero or normal position, the lever 62 engages with a pin 88, projecting` from a second plate 89, (clearly shown in Figs. 6 and 7,) sliding over the cover-plate 17 and having a vertical slot to enable the dial-markings to be seen. The plate 89 has a bridge 90, connecting it to a plate 91, which slides over the plate 2O at the back of the dial. A spring 92 upon a spindle 93, fixed to the bridge 19 and passing through bridge 90, tends to keep the bridges apart; but when said spring is compressed by the action of the lever 62 on the pin 88 one bridge is brought down toward the other and all the plates slide together until the bracket 29 at the foot of the cover-plate 17 passes under the hook 28 upon the sliding bar 30 referred to, and is thereby held down. It is also required that when the lever 62 has been pulled down it cannot be returned until the dial Whichhas upon the casing of the apparatus, normally projects into the path of the lever-arm 613 un- IOO IIO

der influence of a spring 92, and when the lever 62 is pulled down said hook is pushed aside until the lever-arm has passed, when it passes over it and prevents its return. In this position an extension 93 from the hook is in the path oi a bracket 94 xed upon the dial, and when the dial is returning to zero said extension is struck and the hook moved back out of engagement with the lever.

To prevent the dial from revolving back to starting-point with too much impetus, a brake is employed. (Shown in Fig. 2l.) Said brake consists of a lever 95, pivoted at one end 96 upon the casing of the apparatus and having a projection 97 engaged by the arm 63 when the main lever is pulled down, the lever being thereby pressed down upon the periphery of the dial, and a spring 98 draws the brake out of contact with the dial, when the main lever is raised.

XVe will now describe the registering arrangement, which is shown more particularly in Figs. 6 to 8. A lever-bracket a is pivoted in a bearing b, attached to the sliding plate 20. A reel of ribbon-paper c is carried on a stud c', projecting from lever ce, the paper being led around a rubber pressure-roller c2, journaled on the lever, and from thence passed between a roller c, ixed upon a spindle c, journaled in the lever, and a roller c, at the end of a spring c, secured to a projection c7 from said lever. Roller c3 is caused to revolve by a ratchet-wheel o8 upon its spindle engaged by a spring-pawl c, which is fixed at one end to plate 20. Adetent or retaining-pawl cw being iixed to lever a, the ratchet-wheel is revolved by pawl c, when lever a is vibrated. A carbon or ink ribbon d, similar to those employed upon type-writers, is carried upon a reel d upon a spindle cl2, fixed to lever (L, the ribbon being led around a curved hinged bracket cl3 beneath a roller di, journaled upon the pivot-pin d5 oi' said bracket, and from thence carried to a reel d, journaled upon a spindle dl, iixed to lever a. The reel CZG is partially revolved at intervals by an escapement-wheel ds, to which it is connected, and which is engaged by a projection d" upon a disk d10, carried upon the same spindle as ratchet-wheel C8. The object of the hinged bracket d3 is to keep the ink-ribbon out of contact with the paper ribbon except when contact is required for printing purposes. It is shown clearly in Figs. 6 and 8 and has an extending arm d10, which engages withv a pin d upon the lever a, and a spring C112, which engages with a pin Z13 upon the same bracket and limits its upward movement. An aperture d is provided to permit the paper ribbon to be pushed through into contact with the ink-ribbon CZ and simultaneously the ink-ribbon into engagement with the cost-recording type upon the dial, when lever d is operated in the following manner: The upper end of lever o; is formed with a cam-race a', kept in contact with a cam-roller c?, carried upon a bracket a3, fixed to the slide-plate 91 by a spring a* between said plate and the lever. lVhen the main operating-lever 62 is operated, the bridge 90 in moving down toward the bridge 19 takes withit the plate 91, to which is attached the cam-roller (1.9'. Then said cam-roller is moved down a short distance, the shape of the cam-race a' allows the end of the lever to spring out under pressure of the spring ai, and the opposite end of the lever carries the pressure-roller, with the paper ribbon around it, into contact with the ink ribbon through the aperture in the hinged bracket and the ink-ribbon into contact with the registering type, so that the paper receives a printed record of the cost of the article upon the scale. The curved hinged bracket dJ is pushed back by contact with the dial. A further downward movement of plate 91 causes the cam-roller a2 to force the upper end of the lever inward, and the paper and ink ribbons are withdrawn from the type, the spring-catch d'2 upon the arm d10 causing the hinged bracket d to keep the ink-ribbon away from the paper ribbon. The outward movement of the upper end of the lever-bracket a also causes the spring pawl ci to revolve the ratchet-wheel through one tooth and causes paper ribbon to be drawn olf the reel c and delivered outwardly between the rollers d and We will now describe an arrangement by means of which the total weight is indicated of a number of articles weighed upon the weighing-machine, referring now lnore particularly to Figs. 9 and 10 oi the drawings. A bracket c, extending upwardly from the bearing e, carrying the dial-axle 13, has a lever-arm e2 pivoted upon it, which carries at its opposite end a counter c, of ordinary construction. Lever-arm e2 has a tube c iixed upon it, in which works a plunger c", a part of which extending above the cylinder has a spring c coiled around it, bearing between the end of the cylinder and a head cT upon the end of the plunger. 'When thelever-arm 63 is operated, as hereinbefore described, its end engages with the head c7 and forces the lever-arm c2 down until a pinion es, attached to and driving the counter, comes into gear with a spur-wheel c", xed upon the dial-axle. A bracket elo, to which is attached a spring e, assists to prevent the pinion being forced too deeply into gear with the spur-wheel, downward motion of lever-arm 63 beyond that necessary for the purpose being taken up by the plunger e5, passing into tube e4. By the above arrangement the counter is only in gear when a weighing has been performed and the dial is returned to cZero.

Any one of a large number o1' existing' counters can be used for our purpose. One with which we are acquainted is shown diagrammatically in Fig. 10. rPhe short cylinders f f6, having a common axis, have numerals l to 10 upon their circumferential peripheries. The right-hand or unit cylinder j is connected directly to pinion c,

IDO

IIO

before referred to, and is caused to y:revolve (by arranging the relative sizes of the spurwheel e9 and pinion es) through the space of one numeral for each pound weighed upon the machine. At the end of each revolution a projecting pin f2 engages in' a tooth of the ratchet-wheel f3, made integral with a pinion f4, which gears with internal teeth cut in the second or tens cylinder f5, which is thereby moved through the space of one numeral upon its periphery. Cylinder f5 has also a pin f2, which at each revolution actuates a ratchet-wheel f3, giving motion to the third cylinder f6, as described in regard to We will now describe the principal operations ot' apparatus in the order in which they are performed. The lever G2 is normally kept in itsraised position, and the action of balancing an article upon the scale by means of the weighing-bob causes the slide-block 3 to be moved along and the dial to be revolved by the sprocket-wheels 7 l0 l2 and drivingbands 5 and ll. One of the push-buttons actuating the cost-indicating apparatus is then operated and the cover-plate allowed to rise and to show through an aperture the cost of the article. The rising of the cover-plate locks the dial by the retaining-catch 7S, and the lever is then pulled down, thereby pressing down the plate S9 by means of the pin 8S and actuating the recording mechanism. Continued movement of the lever brings the cover-plate 17 back to zero and sets the dial free, while the arm 63 upon the lever 62 releases the weighted plunger 55 and at the same time throws pawl SO out of engagement with the sprocket-wheel 7, and the dial returns to zero. The arm 63 also brings the pinion upon the counter into gear with the spur-wheel, andthe weight of the article in pounds is thereby totaled upon the counter. The lever G2 is then raised, and the cycle of operations is complete.

Having now particularly described and ascertained the nature of oursaid invention and in what manner the same is to be performed, we declare that what we claim isl.
